Nova Pro is supposed to have capacitive touch and a Wacom stylus, but NO frontlight.

Other than that, I believe that they were to be the same.

That said, things may have changed now that they are coming out with a Note Pro which is to have capacitive touch, Wacom stylus and a frontlight... So perhaps they will now also offer a frontlight with the Nova Pro and maybe increased internal storage.

Things may change yet. My advice would be to wait the extra few months if you can do so. Firm specs probably won't be available until closer to the release date.
